Premiere Elements 10: Choppy Playback Issues!

I'm having playback issues in PE10. After reading many forums and converting the MOV video in other formats i found i was still having the choppy playback making it very hard to edit my videos! My computer is a new high spec pc bought purposely for editing my videos yet i'm frustrated with editing because of this problem so i contact adobe help chat. After answering many questions the help operator determined that my graphics card may be the source of the problem as its not listed on the supported devices. My card is a AMD Radeon HD 6500 series. This is a new custom built computer so is it possible that this card has been made after PE10 and therefore not compatible with PE10? If so can adobe make a update that includes newer graphics cards or is there a patch i can download? Either way i am unable to edit anything that i record on my Canon IXUS 220 hs as it takes forever and very difficult. Any ideas anyone?

Hi Scott, I'm in the same boat as you. I have a new 64 Bit dedicated custom video editing PC with Windows 7, twin core proc with a full house on Ram, graphics card is a Geforce Gainward.
Data load up is slow. Playback is erratic and occasionally freezes especially when using caption supers when in edit mode. Sound is unaffected.Playing in
full screen mode is sometimes smooth more often after initial loading. As you say it makes for a hit and miss on the editing.
I also get the occasional organiser crash. I am using hi def avchd files shot on a Panasonic HDC-SD800
Can't anyone help us please?

Premiere Elements in Windows has so much errors,is slow, crashes often. I experimented with v.9 and v10, switched betweeen Vista and Win7, between 32bit and 64bit versions, but it is ALWAYS buggy.

Then I asked a friend with a Mac to install the Elements 10 trial version on his OSX, and everything worked as if by magic, although it is the very same application as in windows.

So it is some sort of Microsoft bug in their OS-Architecture or bugs in the windows version of Apple Quicktime v7.x.

Premiere uses QuickTime to render the files,in OSX it is baked into the system and in windows it is a extra installation. Monitor Windows via taskmanager when you have Prel open and do render video. You will see a "AdobeQuickTimeServer" Task, a "Dynamic Linker" and a "GPU Sniffer" .. it sounds not only horrible , it must be a nightmare that the application must talk in the background to various subprocesses and other applications to do what it should do. Somewhere in this interaction must be the problem under Windows OS.
